2018 $10 1/4 oz Gold American Eagle Proof 70 Coin Description:
The Gold Bullion Act of 1985 authorized the U.S. mint to begin producing gold bullion coins. Every year since 1986, the Gold American Eagle has been minted in both bullion and proof versions, except in 2009, when the proof version was not produced. The first year the Gold Eagle proof was only made in 1 oz. The next year it was made in 1 oz and 1/2 oz. In 1988, they started making four proof sizes: 1 oz ($50 face value), 1/2 oz ($25), 1/4 oz ($10), and 1/10 oz ($5).
